I have a couple of GS's but I need help with my 73 Z28. Engine was running great when I pulled it in OCT to reseal everything and repaint. After putting back in, I have a noise while cranking, and running. Tink Tink Tink Tink etc.. Getting some contact internal. I did not remove any internal while engine was out. I did remove the cam gear and timing chain but left the crank gear on it. I thought I took care to put back before anything was moved. Could I have gotten the cam out of sync with the crank? Yesterday I did a compression test. I also just noticed I have oil dripping from my passenger side exhaust at the seam where the down pipe meets the level portion of the pipe. Is this pointing to the timing chain being reinstalled wrong? Compression Test: 1 - 140 2 - 145 3 - 142 4 - 145 5 - 140 6 - 115, again at 92 7 - 130 8 - 140 Appreciate any assistance. Not getting any responses on the chevy board so far.
